Adolescent Blood Pressure and Early Age Stroke.

Background: Underdiagnosis of relevant risk factors has contributed to the increasing stroke incidence in young adults. Blood pressure cut-off values for adolescents are neither sex specific nor based on cardiovascular outcomes.

Methods: This nationwide, population-based, retrospective cohort study included all Israeli adolescents 16-19 years of age who were medically evaluated before compulsory military service from 1985 to 2013, including routine blood pressure measurements.

Anemia rates after one-anastomosis gastric bypass versus sleeve gastrectomy: a retrospective cohort study.

Purpose: To compare postoperative anemia rates after one-anastomosis gastric bypass (OAGB) with those after sleeve gastrectomy (SG) in a large nationwide, population-based cohort study.

Methods: We sourced data from the Israeli Bariatric Surgery Registry. The study included a cohort of adults who underwent bariatric surgery (BS) between 2013 and 2017.

The association between normal 50-g glucose challenge test results and risk for future metabolic morbidities: A retrospective cohort study.

Objective: To study the association between normal glucose challenge test (GCT) results during pregnancy and the incidence of future maternal metabolic morbidities.

Method: This was a population-based retrospective cohort study conducted between the years 2005 and 2020. The study included all women aged 17-55 years who underwent GCT as part of the routine prenatal care at the Central District of Clalit Health Services, Israel.

A prior placenta accreta is an independent risk factor for post-partum hemorrhage in subsequent gestations.

Objective: The rate of placenta accreta, a life threatening condition, is constantly increasing, mainly due to the rise in the rates of cesarean sections. This study is aimed to determine the effect of a history of placenta accreta on subsequent pregnancies.

Study Design: A population based retrospective cohort study was designed, including all women who delivered at our medical center during the study period.

Placenta accreta is an independent risk factor for late pre-term birth and perinatal mortality.

Objective: This study is aimed to identify the risk factors for the development of placenta accreta (PA) and characterize its effect on maternal and perinatal outcomes.

Study Design: This population-based retrospective cohort study included all deliveries at our medical center during the study period. Those with placenta accreta (n = 551) comprised the study group, while the rest of the deliveries (n = 239 089) served as a comparison group.
